To avoid the problem of yellowing of the backlight material of the TFT LCD screen, it is necessary to start from many aspects such as material characteristics, usage environment, and driving method. In particular, it is necessary to pay attention to the selection and maintenance of the core components of the backlight module (such as LED lamp beads, light guide plates, diffusion films, etc.).

In the world of smart home devices, appliances, and industrial controls, user interfaces are getting smaller, more creative, and more demanding. The need for displays that can convey information in tight spaces without sacrificing readability has driven the popularity of bar‑type screens. The 2.86 Inch 220×648 Bar‑type Display from Hongjia offers a narrow, elongated format with a resolution of 200×648 pixels and IPS full‑viewing angles, making it suitable for status panels, menu interfaces, and scrolling displays. This article examines the product's specifications, interface options, and customization services, and why it has become a practical choice for designers seeking a compact display solution for smart home, appliance, and industrial applications.

Ordinary LCD screens use CCFL light sources, that is, cold-cathode fluorescent lamps (similar to the scanning lamps in the copy), with one on each side of the screen and a backlight on the back of the display, which is composed of fluorescent substances. The light sources on both sides can be evenly distributed on the back of the entire screen, so that the entire screen can be evenly illuminated. However, due to technical limitations, the brightness of such a display is not completely uniform, but it is difficult to find it. At the same time, the lamp also has a certain lifespan, and it will turn yellow after a long time.

Mr. Huang, an engineer at Shenzhen Hongjia Technology, is pleased to introduce a high-color-gamut, high-resolution 5.5-inch TFT display. Featuring IPS full-viewing-angle technology, this vertical-orientation screen boasts a resolution of 720*1440 and an 18:9 "golden ratio" aspect ratio. It utilizes the mature ST7703 driver IC and supports the integration of a capacitive touch panel. The 5.5-inch IPS screen offers a contrast ratio of 1200:1 and a color gamut coverage of 70%. Its pixel size measures 0.08595 x 0.08595 mm, and while the standard brightness is 600 cd/m², it can be customized to reach 1000 cd/m². The interface type is MIPI.

The causes of flickering streaks on LCD screens involve multiple factors, potentially related to hardware component anomalies, signal transmission issues, or external interference
